The tint of these frescoes is rather yellowish tone sound, marked at times by the remembrance, dazzled on time for a glimmer of the past that looks towards the future, as in the case of the string quartet violinist and American composer Sarah Wallin Huff (1980-), titled Anima Mechanicae (2007) and “dedicated to computers and robots of the future, they will want to dream like humans do”. It is perhaps this faculty dream what makes the melodic lines of this quartet music more human, despite its minimalist and mechanical character.
